GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 380,802, dated April 10, 1888.

Application filed November 1, 1886., Serial No. 317,68l. (No model.)

To all whom it may concern:

Be it'known that I, WALTER MARsH J Acre. SON, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in GasBurners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the to same.

' My invention relates to an improvement in gas-burners, the object of the same being to provide a burner or an attachment to the pillar for the purpose of automatically regulating t5 the flow of gas to be burned.

A further object of the invention is to provide a material from which the regulating devices are constructed or the working parts or surfaces of said devices covered, which will neither expand nor contract by alternate heat and cold, and will not corrode or grow foul by exposure to the action of gas or the atmosphere.

With these ends in view my invention con 2 5 sists in the parts and combinations of parts, as will be hereinafter more fully described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a view in longitudinal section showing my improvement applied to an ordinary burner-pillar. Fig. 2 is an enlarged view in section of the regulator.

In the construction represented in Fig. 1, A represents a gas-pillar of the ordinary construction; and B is the regulator, consisting, essentially, of the hollow cylinder A, open at one end and closed at the other, the cylinder B, also open at one end and closed at the other, and the base or disk C, which is preferably flat and provided at its periphery with an upwardly-turned flange, to be hereinafter referred to.

The cylinder A, while it can be made of thin metal lined with paper, is preferably con- 5 structed wholly out of smooth hard paper, and is provided with an opening, a, formed at or approximately at the center of said closed end. This opening a is of a size sufficient to pass the desired or predetermined quantity of gas to be consumed under the low- I est pressure established as a standard of C0111- mencement of regulatiom-say four-tenths of an inch water-pressure. Under such conditions the hole a would be about'one-sixteenth of an inch in diameter for five feetof gas of about six hundred specific gravity, large holes for more gas and smaller holes for less gas.

The cylinder B, which, as before stated, is

closed at one end and open at the other, is also constructed of paper, or of metal lined with paper, and is provided at its lower end with an outwardly-projecting flange, b, and at a point near its upper or closed end with one or more (preferably a series) holes or openings, 0, the gas-delivering capacity of which is greater than the hole a in cylinder A. Thus, if cylinder A has a hole one sixteenth of an inch in diameter, cylinder B will have a single hole larger, or two holes the aggregate capacities of which will be greater than the hole a.

The base or disk C is preferably fiat and provided at its outer edge with an upwardlyturned flange, d, This disk is also provided with a centrally-located opening of a size sufficient to pass any quantity of gas desired under the low standard of pressure.

The three parts above described constitute the regulator, and are assembled as follows: The cylinder A is placed either end up within a cylinder, B, and are locked to disk 0 by turning the upwardly-turned flange (1 down on the flange b, forming a gas-tight joint. The cylinder A is shorter than cylinder B and of less diameter, and when the cylinder A, which is free to rise and fall, is resting on the disk 0 the upper end thereof reaches the bottom or lower edge of the holes.

The device as thus construct-ed is placed within a common burner-pillar, fitting the pillar gas-tight at the point of contact with the turned flange d, and leaving an annular space between the pillar and that portion of the cylinder B which is above the flange d. The pillar is now ready to be fastened to the fixture. As the gas rushes into the pillar, it cannot pass 5 by the flange d, but is forced to enter through the hole in disk 0, and passes up into cylinder B, where it comes in contact with cylinder A. Now, as the cylinder A is extremely light, the gas passes through the hole in the loo closed head thereof and escapes through the holes in the side of cylinder 13. If the gaspressure be, say, four-tenths of an inch, just five cubic feet will pass per hour. If the press ure rises above this, it exerts its force against the cylinder A and lifts same until the upper end of it rises above theloweredges of the holes, and consequently diminishes the quantity of gas escaping from the cylinder B by decreasmg the sizeof the escape-openings in said cylinder. This rise and fall of the cylinder A regulates the flow of gas with great precision. It will be seen that it is absolutely necessary to have the cylinder A extremely light, because it is so small that but little lifting-power can be exerted by the gas. For example, the cylinder weighs one-half a grain, and its diameter is onequarter of an inch. Therefore, as gas under four-tenths of an inch pressure exerts a lifting force of seventy-eight and eight-tenths grains against a circular inch, it would exert a pressure of only four and ninehundred-andtwenty-five one-thousandths grains against a quarter-inch circle. Now the tip or outlet in the pillar must hold the gas back to create sufficient pressure to hold the flame in proper form and consume the gas perfectly, and this reflex pressure is best at two-tenths of an inch. Therefore, with twotenths reflex pressure working back upon the cylinder, we have only three-tenths actuating-pressure, (or, say, three grains,) and as the cylinder Weighs but half of one grain this pressure is sufficient. The above device can be applied to any of the pillars now in common use.

The advantages of paper surface are evident, and the necessity for a paper cylinder is promi nent, since it must be non-corrosive, fixed in form, and exceedingly light.

, It is evident that many slight changes might be resorted to in the form and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

As a new article of manufacture, a gas-regulator constructed and adapted to be applied to an ordinary gas-burner, and consisting of an inverted-cup-shaped shell or cylinder, B, open at its lower end and closed at its upper end and provided near its upper end with a series of openings, 0, an inner and movable inverted cup-shaped shell or cylinder, A, of less length than the outer cylinder and open at its bot tom, and provided with the opening a in its upper end, and a perforated disk or cap, 0, secured at its outer edge to the lower end of cylinder B, whereby all of the parts of the regulator are secured together, the lower end of the regulator being provided with an outwardly-projecting flange to insure an annular space between the outer cylinder and the pillar, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
